Ultra realistic cozy couple portrait

Recreate as an ultra-realistic romantic photo of a young South Asian couple sitting close on a heritage balcony. Preserve both reference faces and natural features. The woman wears a powder-blue sleeveless top, white pleated skirt, and pearl jewelry, holding a yellow sunflower. The man wears a blue-striped shirt and cream trousers, leaning against her while holding a pink flower. Their hands gently intertwine. Insert discreet watermark in the lower right corner of the image, vertical text (rotated 90°), written "aipromptlabs.online", Calibri Light font, white color with low opacity (semi-transparent), medium size. Extreme sharpness on the face, fabric texture and typography of the letters. Shot on Canon EOS R5, 50mm f/2.8, studio light.
